PEEK 3D Printing Filaments - High Performance Additive Manufacturing Solutions
PEEK (Polyetheretherketone) 3D Printing Filaments are high-performance thermoplastic polymer filaments designed for Fused Deposition Molding (FDM) or Fused Filament Fabrication (FFF) 3D printing technologies. The wire is made from PEEK resin through a precision extrusion process and is designed to provide 3D printed parts with excellent mechanical, thermal and chemical properties for a variety of applications.
Outstanding Properties of PEEK Filaments
Parts printed with PEEK Filaments inherit the inherent properties of the PEEK material, and the main performance indicators are as follows:
High Thermal Stability
Long-term Continuous Use Temperature (CUT) up to 250°C (482°F).
Heat Distortion Temperature (HDT @ 1.8 MPa).
Unfilled PEEK: Typically > 150°C (302°F).
PEEK-CF30 (30% Carbon Fiber Reinforcement): Typically > 300°C (572°F).
Excellent Mechanical Strength
High tensile strength and stiffness at elevated temperatures.
Unfilled PEEK tensile strength: typical ~90-100 MPa.
PEEK-CF30 tensile strength: significantly higher, typically > 150 MPa.
Excellent fatigue and creep resistance.
Excellent chemical resistance
- Resistant to organic solvents, acids, alkalis, hydrocarbons and other corrosive media.
Excellent wear resistance
- Low coefficient of friction, high wear and scratch resistance.
Inherent Flame Retardancy
- achieves UL94 V-0 flame retardancy without additives.
- Low smoke and toxic gas emission during combustion.
PEEK Filaments production process of Allstar Material
Dalian Allstar adopts advanced precision extrusion process to produce PEEK wire. The process includes:
Raw Material Screening and Drying
PEEK resin is selected and fully dried with specialized equipment to ensure that the moisture content of the material meets the extrusion requirements and to avoid printing defects. Our process requires that the Moisture Content is kept below 0.02% (w/w). Typical drying time is a minimum of 4 – 6 hours at 120°C to 150°C in a specialized wire dryer or vacuum oven, and 8 – 12 hours or more for high humidity environments or long term exposure.
Precise Temperature Control
The temperature of each section of the extruder is precisely controlled to ensure that the PEEK material is uniformly plasticized in the optimum melt state. The Feed Zone is controlled at approximately 260 degrees, the Melting Zone at approximately 350 degrees, the Metering Zone at 360-390 degrees, and the Die at approximately 400 degrees, which is the highest temperature in the entire temperature system.
High-precision Die and Online Diameter Measurement
High-precision die head, real-time monitoring of wire diameter through the laser online diameter measurement system, diameter tolerance can be guaranteed within ±0.03mm, to ensure the stability of the printing process and part precision.
Controlled Cooling and Uniform Winding
Controlled cooling rate ensures uniform crystallization of the wire to avoid internal stress. The automated winding system ensures that the wire is neatly aligned and free of tangles and knots.
PEEK Filaments Classification
ALL STAR Materials offers the following main categories of PEEK wire to meet the needs of different applications:
Unfilled PEEK (PEEK Natural)
Provides the intrinsic properties of PEEK material with excellent toughness, chemical resistance and biocompatibility potential (medical grade to be confirmed). Suitable for general purpose high performance parts.
Carbon Fiber Reinforced PEEK (PEEK-CF30)
is filled with 30% (w/w) high performance carbon fibers.
Significantly improves stiffness, strength, dimensional stability and thermal conductivity over unfilled PEEK. Ideal for lightweight, high-strength structural components and fixtures.
